Monday Geology Picture(s): Stunning Shots of Santorini

Geology Word of the Week: C is for Columnar Jointing

def. Columnar Jointing: A structure that forms in rocks (most commonly in basalt) that consists of columns (mostly commonly hexagonal in shape) that are separated by joints or fractures in the rock that formed when the rock contracted, most often during cooling. Columnar jointing is always a joy to observe in rocks in the field. Stumbling upon perfectly geometric columns of rock can only be described as magical. Even the …
